Our High-Performing Core Network

Fully virtualizable on VMware, K8S, Docker and OpenStack containers

N3IWF (Non-3GPP InterWorking Function)

N3IWF (Non-3GPP InterWorking Function) is responsible for connecting untrusted non-3GPP access network to 5GC. UE and N3IWF establish an IPSec tunnel, N3IWF connects to the User Plane and Control Plane of 5GC through N2 interface and N3 interface separately.

Key Benefits

5GC Integrated with Satellite Technology

The core network of satellite communication system adopts the same architecture as the ground 5GC. The network functions located in the control plane provide service functions through service-based interfaces, and other network functions can reuse the service functions of a certain network function.
In addition to the basic services provided by 3GPP, in order to support the integration with the ground, it is necessary to add N3IWF network functions on the user plane of 5G Satellite Core Network:
Support the establishment of IPSec Security Association (IPsec SA) with UE, forward the NAS signal of uplink and downlink control plane between UE and AMF, forward packets of uplink anddownlink user plane between UE and UPF, perform N3 packet marking corresponding to QoS, and perform local mobile anchor function in non 3GPP access network.
